COLTER FOR PLOWS.

SPECIFICATION forming part of Letters Patent No. 327,872, dated October6, 1885.

Application filed January 24, 1885. Serial No. 153,884.

To all whom it may concern Be it known that I, OZIA A. ESSIG, a citizenof the United States, residing at Canton, in the county of Stark andState of Ohio, have invented certain new and useful Improvements inOolters for Plows, of which the following is a specification, referencebeing had therein to the accompanying drawings.

Figure 1 is a side view of aplow having my improved colter attachedthereto. Fig. 2 is a perspective view of the colter and the devices forattaching it to the plow. Fig. 3 is a view from the land side of theplow, showing a colter of slightly-modified form.

In the drawings I have shown all of the parts of a plow; but theinvention to which this patent relates more particularly can be appliedto any of the many styles of these implements. A brief allusion to theseveral parts will be sufficient herein.

A represents the beam, B the handle, 0 the standard or post, D thelandside, E the mold-board, and F the point, each and all of which canbe varied as may be desired.

To the parts above described I attach my improved colter, the inventionrelating, broadly, to the combination, with the cutting parts of theplow proper, of a colter so mounted that the point of the colter can bekept firmly seated upon the toe or share. In the drawings, G representsthe colter proper, it consisting of a bar of metal with a sharp forwardedge, 9, the length of the colter being sufficient to reach from thesurface of the soil to the toe of the plow. It may be made reversible,so that when one end has been sufficiently worn it may be inverted andthe other brought into use, though I do not wish to be limited to such aconstruction, and have shown in Fig. 3 one which is not thus reversible.At one or both ends it is beveled on the rear edge, as shown at 9, sothat it may be inclined somewhat and yet fit snugly within the socket orseat provided for it at a in the toe or share.

In order to prevent the toe of the colter from springing out of place inthe socket or recess in the point should it meet with an obstruction, Iemploy a tension or tightening bolt, H, which draws the colter into itsseat, and which at one end engages with the colter,

(No model.)

and at the other has a nut, 71, engaging with the rear side of the post.This bolt may be mounted and connected at the ends with the respectiveparts in any of various ways. As shown, the bolt has a head, h, seatedin a countersunk recess, the longer part of the bolt being bent at anangle to that part which carries the head, and said longer part ismounted in a groove, t, formed in the plate I, by which the upper end ofthe colter is fastened to the standard or post.

Preferably, the parts I and G are pivotally connected, the rigidity ofthe colter being attained by means of the bolt; but I do not wish to belimited to such construction, as the invention may be applied when theparts are otherwise constructed.

The specific construction shown is cheap, and for various reasons is atpresent preferred, in which the bar I is cast with the flat surface '5,to bear against the post or standard, with the aforesaid groove i, toreceive the bolt,with an offset at 1?, and with a pivot pin or lug, i bywhich it is joined to the colter.

I is a plate adapted to be clamped against the forward end of the partI, to which it is secured by means of a bolt, 2', and it is preferablyformed with a countersunk socket to receive the end of the aforesaidpivot-pin i 0 is a bolt passing through the standard and uniting to itthe bar I, this bar being further supported, when the colter is inplace, by reason of the rear end of plate I embracing the front edge ofthe standard and overlapping, for a short distance, the face of thestandard opposite to that against which part t" of the bar I lies. Thecolter can be removed from between the bar I and plate 1, between whichit is confined, by simply withdrawing bolt i, when plate I can beremoved, after which the colter can he slipped off from the pin 5 andremoved, the nut h having been unscrewed from bolt H to allow it to bewithdrawn with the colter. These changes, it will be seen, can beeffected without necessitating the removal of bar I from the standard.

After the parts have been placed in the position shown in Fig. 1, thenut h is drawn up tightly, which insures that the lower end or toe ofthe colter shall be held firmly in the position against all of the usualdisplacing agencies.

The bolt H is situated, preferably, above the line of the top of thesoil, so that it shall in no wise interfere with the proper cutting orturning of the latter.

I am aware that a colter consisting of a cutting-bar attached at itsupper end to some portion of the plow, and at its lower end seated in arecess in the plow-point, and provided with bolts or other means forconfining its lower end in said recess, is old, and I do not claim suchcombination, broadly.

What I claim is 1. The combination of a plow, the bar I,

Y secured against one face of the plowstandard,

the plate I, clamped against the forward end of bar I and overlappingthe face of the standard opposite to that against which bar I lies, thecolter supported at its upper end by bar I, and having its lower endseated upon the upper surface of the plow-point, and the tension bolt H,which holds the point of the colter in place, substantially as setforth.

2. The combination of a plow, the bar I,

secured against one face of the p10 w-standard, and provided with agroove, 2', in its inner face, the plate I, clamped against the forwardend of bar I, and overlapping for a short distance the face of standardopposite to that against which bar I lies, the colter supported at itsupper end between bar I and plate I, and having its lower end seated ina recess in the plow-point, and the tension-bolt H, lying in said groovei between the bar I and the standard, having its front end attached tothe colter and provided with a nut, 71, which engages with its rear endand bears against the rear edge of the colter, substantially as setforth.

3. The combination of a plow, the reversible colter G, having its lowerend seated upon the plow-point, the bar which supports the upper end ofthe colter, and a tension-bolt which holds the point of the colter inits seat, substantially as set forth.

In testimony whereof I affix my signature in.

presence of two witnesses.
